My favorite scene in "What About Bob" is when Dr Leo Marvin dumps Bob on the side of the road after he is released from the "mental hospital" thinking he is rid of him forever and then Leo gets a flat tire and drives into a ditch further up the road. Meanwhile, Bob catches a ride and passes him along the way to further ingratiate himself with Bob's family.
That was a great black comedy.
